摘　　要：新疆某煤矿开采过程中存在火烧区、采空区积水问题,这对煤矿的安全生产构成很大的威胁。根据火烧区及采空区积水前后的物性差异,采用瞬变电磁法进行勘探,根据反演计算所得视电阻率断面图、切片图结合矿区水文地质特征,对勘探区范围内积水情况进行了综合评价。通过后期验证,勘探划分积水区范围准确。There is a fire zone, gob water issue in the process of coal mining, which has great threat to the coal mine safety production. According to physical differences before and after water accumulated in gob and burning area. TEM is used to comprehensively evaluate water accumulated conditions in explored zone with the calculated apparent resistivity inversion cross - sectional views and slices and mine hydrogeological characteristics. Through post - verification, the results of the exploration is accurate.
